Definitions

  • the invention relates to an apparatus for remotely controllable and programmable positioning of air-cooled devices, more particularly studio flood lights, which are adjustable in elevation, are rotatable about a vertical axis and swingable about a horizontal axis.
  • the positioning apparatus is to be remotely controllable and programmable.
  • an apparatus for adjustably positioning an air-cooled device includes a housing which is rotatably mounted to be rotated by a drive motor.
  • the housing is connected to an air blower or air suction device.
  • This housing contains a motor driven winding drum associated with a spring mounted pressure drum.
  • a flexible, preformed or pretensioned elastic winding tape runs off the winding drum and through a cylindrical guide opening from the housing such that due to the tapes preformation and pretension the tape is transformed into a stiff air-conducting tube.
  • a motor drive or remotely operated swingable holding device for the air-cooled device that is to be positioned.
  • the electric lines for the drive motor of the swingable device and/or air-cooled device are designed as members that are secured to the winding tape or are built thereinto and the said lines are wound or unwound together with the tape.
  • a second winding tape or a number of winding tapes may be assigned to individual associated winding drums in such a way that the two or more winding tapes overlap one another oppositely offset from one another in a common tubular shape.
  • the drive motor of the winding drum may be designed as a continuously running electric motor coupled to a counting device, the counting impulses of the counting device being proportional to the length of tube that is fed out of the housing.
  • the drive motor of the winding drum may, however, also be designed as a stepping motor, the number of the prescribed incremental steps being proportional to the length of tube that is fed out of the housing.
  • FIG. 1a is a longitudinal section through the housing of one embodiment having one winding drum
  • FIG. 1b is a section through the tube 2;
  • FIG. 1c is a partial section through the swingable holding device and air-cooled flood light
  • FIG. 2a is a longitudinal section through the housing of a second exemplifying embodiment having two winding drums;
  • FIG. 2b is a section through the tube comprising two tapes
  • FIGS. 3, 3a and 3b illustrate the subject matter of FIG. 2 with a drive
  • FIG. 4 is a schematic showing in plan view of a third embodiment having three winding drums.
  • a first exemplifying embodiment of the invention illustrated in FIG. 1 comprises a housing 13 rotatably mounted by conventional means in a stationary member or base 23.
  • the housing 13 contains a winding drum 15 journaled therein on which is wound a tape 8 of flexible preformed or pretensioned elastic material.
  • the tape emerges from housing 13 through a cylindrical guide 24 and in so doing, is transformed as the result of its preformation and pretension into a tube 2 whose longitudinal edges overlap one another.
  • Stainless steel may be used, for instance, as a suitable material.
  • the air-cooled device 4 is secured to the free end of the tube as hereafter explained.
  • the winding drum 15 may, for example, be set in rotation by way of a transmission member 21 by means of a drive roller 9 journaled in the interior of housing 13.
  • Drive roller 9 is driven by a drive motor 1 disposed on the outside of housing 13.
  • a pressure drum 14 is swingably journaled in the interior of housing 13 and is pressed against winding drum 15 by means of a tension spring 10 so that tape 2, which is tubular in its unstressed state will be wound upon winding drum 15 as a flat tape 8.
  • a drive motor 5 secured to stationary member 23 sets housing 13 in rotative motion about a vertical axis by a gear drive so that housing 13 can be rotated together with tube 2 secured. Air cooled device 4 disposed at the lower free end of the tube is thereby rotated with the housing.
  • a holding device fixed member 17 Disposed at the lower free end of tube 2 is a holding device fixed member 17 and secured thereto a holding device swingable member 12 rotatable about a horizontal pin 11.
  • the air-cooled device 4 is secured to the swingable member 12.
  • a drive motor 6 secured to the fixed member 17 device 4 may be swung about horizontal rotating pin 11 by way of a gear drive.
  • the three drive motors 1, 5 and 6 which can be remotely controlled and programmed making possible an elevational adjustment that is continuous or stepped enables a rotating movement about a vertical axis and a swinging movement about a horizontal axis.
  • a further horizontal movement may be achieved by continuously moving the member 23 (which has been described as stationary) in the horizontal direction by means that are not shown but are well known.
  • a slotted opening 19 may be provided into which the outside air is sucked in the direction of arrows 18.
  • the heated cooling air then moves upwardly in the direction of arrows 16 in the interior 7 of tube 2.
  • Conduit 23' connects the housing and an air suctioning device 22 (fan).
  • the electrical lines 3 that are required for device 4 and drive motor 6 are secured in flattened form to the outside of winding tape 8 or are incorporated into the tape so that the cable 3 and winding tape 8 can be wound up together on winding drum 15.
  • FIG. 2 illustrates a second embodiment in which two winding drums 15 and 15' are journaled opposite to one another and turn on parallel axes.
  • the two winding tapes 8 and 8' are thus wrapped around one another and when being unwound form a rigid, airtight tube.
  • FIG. 3 illustrates a modified embodiment of FIG. 2.
  • the winding drums 15 and 15' do not rotate together since the transmission 21 of FIG. 2 has been omitted.
  • the unwinding of the tapes 8 and 8' and consequently also the elevational adjustment of device 4 is accomplished for winding drum 15' by means of drive motor 26 by way of gear 27' and for winding drum 15 by way of gear 27 which meshes with gear 27'.
  • Drive motor 26 also serves to swing device 4 about a horizontal axis 32. To do so, gear 27 and winding drum 15 are blocked by magnetic brake 28. Winding drum 15' is uncoupled from the housing of drive 30 and gear 27' connected thereto by coupling 29. Now drive 26 drives winding drum 15' by way of the inner portion of drive 30. Thus only winding tape 8' is wound or unwound and by way of lever system 31 adjusts the flood light 4.
  • the drive In order to achieve small changes in the angle of swing, the drive also contains a strong reduction of the drive into "slow.”
  • FIG. 4 An even greater rigidity of the tube may be achieved by the third embodiment shown schematically in FIG. 4, in which three winding tapes 8, 8' and 8" are used and wrap themselves around one another. In this way any desired degree of rigidity and load carrying capacity of tube 2 can be achieved corresponding to the weight of device 4 and the length that is being run out.
  • the apparatus described can be remotely controlled and programmed when the three electric drive motors 1, 5 and 6 are connected to corresponding electrical signal emitters and counting devices.
  • the said drive motors may also be designed as stepping motors so that the number of the prescribed impulses will be proportional to the run-out length of tube 2.
  • the control signals may be fed in manually and then be converted into electrical signals or they may be read off by a data memory.
  • a programmed positioning system of this type will allow the device that is to be positioned to enter any desired elevational or angular position.
